Abstract

A finger follower assembly (30) for variably activating a valve of an internal combustion engine having a camshaft with at least one lobe (40). The finger follower assembly includes a follower body (54), a shaft (78), a cam follower (56), and a latching mechanism (58). The cam follower is supported by the shaft and is configured for engagement with the at least one lobe. The cam follower is configured to pilot on the camshaft to maintain an alignment of the cam follower with respect to the at least one lobe. The latching mechanism selectively latches and unlatches the cam follower to the follower body to provide a first valve lift capability and a second valve lift capability.
